The Skywatcher Quattro series are premium quality imaging Newtonians with a wide field of illumination and fast f4 focal-ratios. Tube interiors have knife-edge ray traced baffles.
Carbon fibre is a strong and lightweight material with better thermal stability than steel. This is especially important for astro-photographers dealing with long exposure times. Imaging telescopes made of less thermally stable material can deviate from optimum focus after long time exposures. With a carbon fibre tube, it can remain in focus for a longer period of time.
PYREX MIRRORS: Paraboloidal primary mirrors made of low thermal expansion Pyrex glass resulting in shorter cool-down times.
